# What's the area of effect for the Scarecrow?

So after having some jerkass crows steal some crops for the first time I immediately put up a Scarecrow, since it'll keep the crows away. However, it has a limited range of 20 tiles, as seen in the description:

So my first thought was this meant that any tile within 20 tiles of the scarecrow would be immune to crows, but I've been poking around online and I'm getting mixed information on how it actually works. Some folks are saying it's a circle with a diameter of 20 tiles, and others are saying it has a radius of 20 tiles (some folks are saying the area is shaped as a square instead of a circle which makes a difference as well). Knowing exactly how this scarecrow works is important to knowing proper placement of them, so I'm looking for a definite answer on how it works.

Can anyone confirm how the scarecrow works via either SCIENCE! or a statement from the developer?

• According to an item in the 1.03 changelog: "Scarecrow range reduce to 8 tiles radius." I would assume, based on the word "radius" and the grid system of the game, that the area of effect is 8 tiles in any direction, yielding a square of 17 tiles on a side (8 + 8 + 1 tile for the scarecrow itself).
